Mine turns off too. If the app is left on in the background for a while, I have to touch to turn it back on. Before the upgrade I did not have to do this. My flash does not turn on when the HDR is off, I just have to turn the HDR back on because it turns itself off, no HDR and no flash. Not really that big of a deal, it just takes an extra step to turn it back on

I turned on HDR and have been closing the app, removing it from my recently used apps list, and then opening the app. So far it's stayed on. I take a lot of pictures so I'll know by tomorrow if it's going to stay on or not.

That's interesting I'll have to try that out. I'll report back. I just removed it from the tray, instead of leaving it open in the background. I'll give it 30 min. and then try it out.

Mine's doing the same since updating to iOS 7.0.3. I'm on an iPhone 5. Even closing out the app and then re-opening it doesn't fix it. Stays off and I have to manually toggle it back on?!

Same here I just tried opening up the app after having it closed for 30 minutes and I had to reenable HDR once again. It doesn't matter if the app is running in the background or not I will always have to reenable HDR. It's kind of annoying, especially because it worked flawlessly just a couple of days ago before I updated to 7.0.3

It's not a feature, it's a bug. The HDR option is supposed to be persistent. Currently HDR randomly turns off when switching back into / relaunching the photo app. Sometimes it stays on, sometimes it doesn't.

Some people choose to shoot HDR for all individual shots.

What I've noted:
- If HDR is on, and the camera app is force quit and relaunched, it stays on.
- If HDR is on, and the camera app is backgrounded then switched back to within a short time frame, it stays on.

It seems to only be an issue if the OS decides to kill the backgrounded camera app to free up resources. Then when you relaunch it, it comes back as disabled. More confusing is that the saved image of the camera app still has HDR set to on, so for the first quarter second or so, it appears to be on, but then flips back off as the cached image is replaced with the real app output.
